Abstract： Strengthening thequalitycontrolofflyash isparticularlyimportantforimproving thecomprehensiveutilization value of fly ash in China. Based on this，the quality parameters of fly ash （such as 45μm sieve residue，particle size distribution，lossonignition，waterdemandratio，flowability，chemical composition，and particlemorphology）were mainly studied.The influencingfactors offlyashqualityandthe interactionbetween various parameters were analyzed，and the variationlawoflyashqualitywasobtained.Thesmallerthefinenessoflyash，thesmalerthelossonignition，thelower the waterrequirementratio，the betertheflowability，the higher thecontentof glassmicrospheres，andthe strongerthe activity，thebetter the qualityoffly ash.
